Off-Highway Recreational Vehicles

This page last reviewed December 10, 2014


Introduction

Welcome to the California Air Resources Board's (ARB) off-highway recreational vehicle (OHRV) regulatory activity home page.  OHRVs primarily include off-highway motorcycles, all-terrain vehicles (ATV) and utility-terrain vehicles (UTV).  Although their categorical name only acknowledges the segment's recreational aspects, OHRVs are frequently used in occupational disciplines that include, but are not limited to, agriculture, building and trades, landscape maintenance, and law enforcement.  Spark ignited OHRV's are a known source of tropospheric ozone precursors that contribute to the formation of photochemical smog.  In response to their air quality impact, ARB began regulating OHRV emissions as early as 1994.  For additional information regarding ARB's OHRV and associated regulatory programs, please click the links provided on this page, or those provided in the left margin under "Program Links."
